My 1st language is Russian, which is probably the most cluster-friendly of the major world languages, with the possible exception of Polish (e.g., kontrprimer, vsprygnut' ...).

I dunno about most...over in the Caucasian languages you run into things like Georgian's gvprckvni "You peel us" (he said, relying entirely on Wikipedia for the word and translation, due to a total lack of familiarity with Caucasian languages, or words starting with 8 consonants in a row).

Is that the actual phonetic representation of the word, or just a transliteration from the Georgian alphabet? Some languages don't indicate all the vowels in their spellings, but preserve them in speech - like Arabic, and to a smaller degree Serbo-Croat (Srpski! ) - which is why I ask (I know nothing about Georgian).

Also, I was thinking of the "major" world languages, e.g. the chief UN languages, languages commonly found in diverse locations ... not sure I'd classify Georgian as "major" ... I know there are lots of less internationally popular languages that show a greater affinity toward consonants

Russian is fairly easy to pronounce, actually xD. Fortunately it doesn’t abuse consonants like Polish does. I put Russian on pair with Spanish when it comes to clusters, though Russian may have a bit more clusters.

Interesting - in my experience Spanish is almost as averse to consonants as Italian.

I think where Russian consonant clusters are found often is when you pronounce one of the one-letter prepositions k, v, s between words with consonants. This results in oddities like kljuch v dveri, park v Krasnojarske, which tend to flow together as one word in fluent speech. You never see this sort of thing in Spanish or Italian.

And you are completely right. Spanish phonotactics do in no way compare to Russian. Spanish is even more restrictive than Italian [1]. The only permitted clusters in the onset are muta cum liquida and fl- and fr-. The only permitted cluster in the coda is -ns. So the longest resulting cluster is of four letters: -nstr- but only between syllables as in cons.truc.ción for example.

----
[1] Italian allows initial s+muta (s impura) as in "scuo.la" or "stru.ttu.ra". In Spanish you have to put the s in the coda of another syllable: "es.cue.la" and "es.truc.tu.ra".

Which abuse?

I can't say for certain. I'm not really familiar with Georgian, either. I just know that Caucasian languages are known for being heavily consonantal, and Georgian was the only one I could think of offhand at the time. The example I used was one of two examples used in the English-language Wikipedia article, but the pronunciation was not given specifically. The link is here, if it helps:

But you're right, Georgian may not qualify as a major world language. I read right over that word in your post without seeing it.
